Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489866, here are decompositions:

17 + 2147489849 = 2147489866
23 + 2147489843 = 2147489866
47 + 2147489819 = 2147489866
149 + 2147489717 = 2147489866
167 + 2147489699 = 2147489866
227 + 2147489639 = 2147489866
383 + 2147489483 = 2147489866
443 + 2147489423 = 2147489866

Showing the first eight; more decompositions exist.
